Problem

The default UCS Single Sign-On setup consists of an additional DNS Record that is shared between master and backup servers to provide a failsafe setup.
That default DNS Record is ucs-sso.domainname.
In certain setups, e.g. when operating UCS in a cloud scenario, only one external DNS Record is available for a server.

Solution

The following commands have to be executed to configure the single sign-on identity provider for a different DNS Record.

Warning

This configuration will enable an apache wide suexec configuration for the single sign-on. Webpages and Apps that require cgi scripts to be executed will run into problems, check /var/log/apache2/suexec.log. These programs need to be adapted seperately.
